Description

LOTADER® AX8840 is a random ethylene – glycidyl methacrylate copolymer (E-GMA).
• Glycidyl methacrylate gives reactivity (versus OH, COOH and NH2 groups), leading to optimal dispersion during melt mixing with engineering thermoplastics.
• As an ethylene copolymer, LOTADER® AX8840 is compatible with LDPE in all proportions, and with almost all other ethylene copolymers.

LOTADER® AX8840 exhibits good adhesion on PET, PBT, PPS, metal, paper, glass.
Due to its reactivity induced by the glycidyl methacrylate LOTADER® AX8840 can be used as:
• a compatibilizer for polyesters/polyolefins blends,
• a bitumen performance enhancer / additive for asphalt modification,
• an adhesive for some laminate structures (polyolefins/polyesters, polyolefins/PPS etc.).

Processing

Heat stability of acrylate comonomer allows processing temperatures as high as for polyesters (PBT, PET) and PPS, which are the main material using LOTADER® AX8840 as impact modifier.
CAUTION: LOTADER® AX8840 reacts with polymers containing maleic anhydride and acid.
This reaction may generate gels or can block an extruder if not controlled. Extruders must be thoroughly purged before and after extruding LOTADER® AX8840.

Storage, Handling & Safety

LOTADER® AX8840 should be stored in a ventilated area, away from heat, humidity and direct sunlight. Improper storage conditions may cause degradation and could have consequences on physical properties of the product.
